  • What are the technical information used in electrical work
    • British standards
    • Statutory documents
    • Codes of practice
    • Technical data
    • manufacturers instructions
    • Specification
  • British standards (BS) publications are technical specifications or practices that can be used a guidance for the:
    • Production of a product
    • carrying out a process
    • Providing a service
    Normally the use of standards is voluntary and impose legal responsibilities only when required in specifications and codes of practice
  • What is Code of practice
    • A set of regulations for the design and instillation of electrical wiring in a building
    • It's a set of written rules which explains how to achieve the standards required for safety, conduct, operational integrity and ensure industry compliance with consumer confidence
  • Electrical code
    A set of regulations for the design and installation of electrical wiring in buildings
  • Intention of electrical code
    • To provide standards to ensure electrical wiring systems that are safe for people and property where hazardous and/or unusual operating conditions for design and installation
  • Factors considered in electrical code
    • Electric cables
    • Switchgear
    • Control equipment
  • Electrical code considerations

    • Circuit operating voltage
    • Electric current capability
    • Environmental conditions
    • Ambient temperature range
    • Moisture levels
    • Exposure to sunlight
    • Chemicals
    • Explosive environments
  • Wiring safety codes or regulations
    Ensure both wiring and associated devices are designed, selected and installed so that they are safe for use
  • A technical data sheet is a document that summarizes the performance and other technical characteristics of:
    • A product
    • Machine
    • Component
    • Material
    • A subsystem
    • A power supply
    • Software
    In sufficient detail to be used by any skilled person, technician or engineer to integrate a component into a system or to solve issues within a system or to enable correct instillation and maintenance of a system
  • Manufacturer instructions
    • Contain specific details about the product that are not readily available anywhere else
    • Must cover intended use, ways the product should not be used
    • The manner of installation
    • Correct use to ensure health and safety
    • Safe maintenance, including cleaning
  • User instructions
    Should be comprehensive, easy to understand, and in the user's own language
  • Following manufacturer's instructions
    Will allow one to comply with safety legislations
  • Where an accident occurs and the defendant didn't use manufacturer's guidance and instructions
    It can be used against the defendant
  • What are Specifications
    Document describing the materials and workmanship required for a development
  • Specifications can be incredibly wide-ranging - covering the establishment of:
    • The site
    • The type of contract to be used
    • The performance criteria of the asset
    • The quality of the systems and products
    • Which standards are applicable
    • How they should be executed, and even the products to be used
  • Specifications are used in
    • Construction
    • Aerospace
    • Oil
    • Gas
    • Automotive and Manufacturing
  • What does Specifications not include
    • Cost
    • Quantity or drawn information
    • And so need to be read alongside other information such as quantities, schedules and drawings
  • What is Statutory documents
    • Its the general term that embraces main laws passed by government, and includes Acts of Parliament, Act of pre-UK Parliaments, and Acts of the Scottish Parliament etc.
    • They are used to create new laws or to introduce changes to existing ones.
